Indeed. I am wondering why it was put in a tree and sent to Linus without
any Acks or even being replied to by anyone. It appeared in the tty tree
between Oct 14 and Oct 25 (while I was unfortunately on vacation). If
anyone had tried to boot this on any PowerPC server, it would have been
immediately obvious (as it was when I booted Linus' tree last night).

And the original author expressed doubts as to his understanding of how
it should all work anyway.

Just a little more care, please.

I would vote for reverting the original and having it resubmitted with
corrections at some later date.
